| Popis: | Sheet-type resin floors possess a risk of slipping during rains or liquid spills. We investigated the friction properties of vinyl flooring sheets using shoes and glycerol solution, and clarified the combined effect of the groove's depth and width and a urethane coating on the coefficient of friction (COF). According to the analysis, the static COF could be expressed using the spreading coefficient. All the dynamic COFs could be expressed using the spreading coefficient and aspect ratio of the grooves. All the COFs were significantly affected by the interfacial tension at the triple line but were relatively unaffected by the groove shape. |
